Hi Pat the flow at the bulk head valve does not represent production only sampling. Maybe the best rule of thumb may well be when you make less than 50 l as measure on the float stick change the membrane?

Maybe someone on the site has info on flow gauges and can tell where to buy a float.

How is the mast project going?

Regards and good luck

Thanks for gasket info, I will take another run at it.How about the flow
meter though, can I operate without it.Could I occasionally take a timed
measurement of how long it takes to produce a gallon. Thanks, Pat
